Media binder

A case assembly of a media binder, comprising:

• a front surface board and a back surface board, wherein each surface board comprises an inwardly facing surface and an outwardly facing surface;
• a binding sheet comprising an inwardly facing surface and an outwardly facing surface, wherein the inwardly facing surface of the binding sheet attaches to the outwardly facing surface of the surface board, the binding sheet comprising perforation lines parallel to the spine board and proximate to edges of the surface board;
• and at least one cover sheet, wherein each cover sheet is wrapped around the outwardly facing surface of the binding sheet, and comprises at least one marginal edge attached to the inwardly facing surface of the surface board, and comprises at least one marginal edge unattached to the inwardly facing surface of the surface board, wherein an end of the unattached marginal edge comprises an extra edge extended from the unattached marginal edge, the extra edge is folded against the unattached marginal edge and the unattached marginal edge is attached to the inwardly facing surface of an adjacent surface board to form a corner wrap around a corner of the adjacent surface board.

A media binder, comprising:

• surface boards including a front surface board, at least one spine surface board, and a back surface board, wherein each surface board comprises an inwardly facing surface and an outwardly facing surface;
• at least one binding sheet attached to the inwardly facing surfaces of the surface boards, wherein a binding sheet comprises a component that distributes a bending force on a first region of the binding sheet to a second region of the binding sheet, the second region being larger than the first region, and the binding sheet comprising perforation lines parallel to the spine board and proximate to edges of the surface boards;
• and at least one cover sheet, wherein each cover sheet is wrapped around the outwardly facing surface of the at least one binding sheet, and comprises at least one marginal edge attached to the inwardly facing surface of the surface board, and comprises at least one marginal edge unattached to the inwardly facing surface of the surface board, wherein an end of the unattached marginal edge comprises an extra edge extended from the unattached marginal edge, the extra edge is folded against the unattached marginal edge and the unattached marginal edge is attached to the inwardly facing surface of an adjacent surface board to form a corner wrap around a corner of the adjacent surface board.
